very sad...
This game has many flaws in it. The collision detection needs to be fixed with not just the platforms, but also, the obstacles. When using a familiar character, there must be something that associates with that character, for bomberman it would be puzzles and blowing stuff up. Fix the jumping code, since that was really stupid. The player can jump so high, the player can clear the stage in a few jumps. Test the game yourself to see if you have everything working the way you want it, as well as have others test it to tell you what needs to be fixed. And finally, sound. There are no sound FX to make it enjoyable and the same techno trash constantly playing was aggravating.
There are other flaws, but these are the major ones that you need to take care of. Yeah, it made it through the portal, but that doesn't mean it is good. Try to improve and when learning games, try out simpler stuff before going into making more complicated games like RPGs and Platforming. You should practice quiz games to understand buttons better and maze games to become better acquanted with important stuff like collision detection.
